Struct Stream

Source

pub struct Stream {
    pub dict: Dictionary,
    pub content: Vec<u8>,
    pub allows_compression: bool,
    pub start_position: Option<usize>,
}

Expand description

Stream object Warning - all streams must be indirect objects, while the stream dictionary may be a direct object

Fields§

§dict: Dictionary

Associated stream dictionary

§content: Vec<u8>

Contents of the stream in bytes

§allows_compression: bool

Can the stream be compressed by the Document::compress() function? Font streams may not be compressed, for example

§start_position: Option<usize>

Stream data’s position in PDF file.

Implementations§

Source §

pub fn with_compression(self, allows_compression: bool) -> Stream

Default is that the stream may be compressed. On font streams, set this to false, otherwise the font will be corrupt

Source

pub fn filters(&self) -> Result<Vec<&[u8]>>

Source

pub fn set_content(&mut self, content: Vec<u8>)

Source

pub fn set_plain_content(&mut self, content: Vec<u8>)

Source

pub fn get_plain_content(&self) -> Result<Vec<u8>>

Source

pub fn compress(&mut self) -> Result<()>

Source

pub fn decompressed_content(&self) -> Result<Vec<u8>>

Source

pub fn decompress(&mut self) -> Result<()>

Source

pub fn is_compressed(&self) -> bool

Source §

impl Stream

Source

pub fn decode_content(&self) -> Result<Content<Vec<Operation>>>

Decode content after decoding all stream filters.
